We have summarized all of the important information for safely using WAGO splicing connectors.
Copper (Cu) or aluminum (Al): For electrical cables, it’s not a question of faith, but usually an issue of price. Both have their advantages and disadvantages, but when they come together, things can get dicey. However, electricians don’t necessarily need a specialty Al/Cu connector for building installations. With WAGO Alu-Plus Contact Paste, they can connect aluminum and copper conductors using WAGO’s connectors – quickly, easily and reliably.

In everyday use, product names are often simplified, for example, the “two-five WAGO” or the “one-five NYM.” When product types use a uniform naming scheme, such simplifications are generally adequate. But if they don’t, technical problems could arise due to incorrect product selection!
An example from real life: The dimensions for installation cables and lines used for power wiring, such as NYM lines, are specified in mm2, i.e. by the conductor cross-section. In contrast, dimensions for conductors used for signal and communication purposes, such as doorbell or J-Y(ST)Y conductors, are indicated in mm, i.e. by the conductor diameter. In order to ensure that splicing connectors can be clearly associated with the appropriate conductors, the corresponding WAGO connectors are also designated in the same way.
The connection range of the 2273 Series COMPACT PUSH WIRE® Junction Box Connectors for power wiring with installation cables and lines is specified in terms of the conductor cross-section: 0.5 to 2.5 mm2 (20–14). The connection range of the 243 Series MICRO PUSH WIRE® Junction Box Connectors for signal and communications lines is specified in terms of the diameters: from 0.4 to 0.5 and 0.6 to 0.8 mm.
If the corresponding unit is ignored, it would be easy to get the impression that the new 2273 Series COMPACT PUSH WIRE® Connector for Junction Boxes could also be used for 0.6 mm and 0.8 mm signal and communication lines, since its larger connection range goes up to 0.5 – But that actually refers to the conductor cross-section of 0.5 mm2 (20 AWG)! When converted to conductor diameter, this corresponds exactly to a diameter of 0.8 mm (0.031 inches). This means that signal and communication lines with a conductor diameter of 0.8 mm (0.031 inches) can be connected with the 2273 Series. The 243 Series MICRO PUSH WIRE® Connector for Junction Boxes is available for all conductors with a diameter of less than 0.8 mm.
